panel.qqmathline: Useful panel function with qqmath

Description

Useful panel function with qqmath. Draws a line passing through the points (usually) determined by the .25 and .75 quantiles of the sample and the theoretical distribution.

Usage

panel.qqmathline(x, y = x,
                 distribution = qnorm,
                 p = c(0.25, 0.75),
                 qtype = 7,
                 groups = NULL, 
                 ...)
